Nick Jonas and Selena Gomez have stepped out twice together this week!

Tuesday night, the two (who reportedly dated in 2008 after his split from Miley Cyrus) hit Philippe restaurant in Beverly Hills for dinner. And although they were dining with a large group in the private wine room, a source tells E! News “they were by each other’s side the whole night.”

Their first date was a little more low-key. After Nick did the “We Are The World” recording Monday night, the Disney duo went bowling together.

So is it as serious as it seems?

Maybe. “It’s young and they’re just feeling things out,” a source tells us. “It is not at all as serious as Miley and Nick were. But she’s a cool girl and he’s having fun with her.”

Cute singers with curly hair isn’t the only thing Selena and Miley have in common. A source tells E! that Selena is using record producers Antonina Armato and Tim James on her next album. These are same hitmakers who made Miley’s “See You Again” and “7 Things” (which Miley wrote about Nick after their breakup).

And while Selena and Nick were at Philippe, Miley stepped out to dinner with Demi Lovato, Selena’s BFF. Looks like these two don’t mind sharing!
